SEWING-MACHINE.

$PECIFIGATION forming part of Letters Patent No. 508,600, dated November 14, 1893.

- Application filed January 23, 1893. Serial No. 459,350. (No model.)

To all whom it may concern: I

Be it known that I, GEORGE H. COLLEY, a

' citizen of the United States, residing at J ackson, in the county of Jackson and State of Michigan, have invented certain new and usedie or needles in an ordinary two-needle or multiple-needle rotating shuttle machine having the usual double or multiple sh uttle-race.

Another object is to provide means for multiplying the number of needles that may be actuated by a single driving shaft as ordinarily employed in one and two-needle machines.

A furtherobject is to provide means for' combining a plurality of shuttles and needles without circumscribing or limiting the relative positions of the needles or the number that may beemployed ina particularmachine.

These several obj ects may be attained by the mechanismillustrated in the accoin'panye ing drawingsfin which I have shown two species of the invention applied to a- Singer two needle machine, and in one of which the shuttle-race for the introduction of the third shuttle is formed in separate arcs with a removable or hinged section and means for securing the same in proper position, while 1n the other a number 'of shuttle-races or separable circular sections of a multiple race and needles are combined-in such manner as to permit a greater or less number to be employed and the spacings between the shuttles andneedles to be adjusted as may be desired.

- Other forms may, however, be employed and various changes may bev made in the constructionand arrangement of parts, according to requirements, and to adapt the invention to other types of machines employing rotating shuttles.

The invention will first be described with reference to the accompanying drawings, which form a part ofv this specification, and then pointed out in the claims at the end of this description.

Referring to the drawings by letters of reference, Figure 1, represents a front end elevation of so much of a sewing machine as is necessary to illustrate the application of my invention. Fig. 2, is a bottom plan of the same. Fig. 3, is a side elevation. Fig. 4, is a detail sectional view, the section being taken on the line IV-IV of Fig. 1, with the shuttle in the position shown in Fig. 5. Fig. 5, is a side view of the shuttle-race detached; and Fig. 6,. is a .rear view of the same. Fig. 7, is a detail side elevation illustrating a modification of the invention. Fig. 8, is aside View of the race-way shown in Fig. 7; and Fig. 9, is a detail plan of the needle-holder.

A, denotes the Work-plate of the sewing machine; B, the overhanging arm of the frame or goose-neck which supports and guides the needle-bar O, and presser-foot bar D.

c, c, are the needles, and d, the presserfoot, carried by the bars 0, and D, respectively.

E, denotes the usual shuttle drivingshaft; F, the feed rocker-arm; G and G, the feed rocker-shafts; H, the feed-dog, I, a circular interiorly grooved casing forming the race- .Way, and .K, the, rotary shuttles Working in said grooves or races and carrying the 'usual bobbins. v

'The parts as thus far described: are o'f the usual and well known construction in rotating shuttle machines, and may be operated in they usual way, and therefore further description thereof herein is not deemed necessarv. I

In the ordinary two-needle machine there A are two races formed in a single casting or casing and in the multiple-needle machine a series of races in which the shuttles are con-' as ordinarily constructed. To accomplish this result in an ordinary two-needle machine I provide an intermediate shuttle-race or races '6', between the usual races 11,1, by dividing the race-way casing vertically or forming an elongated circumferential slot I, therein to receive a segment 1 the curved inner face of which is grooved to coincide with the groove in the stationary portion of the race-way and form a guide or race for a third shuttle. The segment I may be secured in position in any proper manner, but for convenience in opening and closing it so as to permit the insertion or removal of the shuttie, the segment is preferably hinged as at 2' and provided with a knob or handle i for turning it upon its hingso as to open or close the shuttle-race. When closed the segment 1 may be locked by a spring-pressed locking pin or bolt L, which slides in a bracket M, underneath the work-plate in position to enter an opening 1', in the race-way casing, which opening registers with a corresponding opening i in the segment. The pin L, is provided with a thumb piece or milled head I, having a peripheral notch Z, which is engaged by and slides along a pin or stud m, projecting from the bracket M, so that the locking pin is prevented from turning until the notch passes the outer end of the stud, as indicated by the dotted lines in Fig. 4, whereupon, by a slight rotary movement of the locking pin, the notch in the head will be turned out of the path of the stud so as to cause the latter to hold the locking pin disengaged from the segment. Thereupon the segment may be drawn out to the position shown in dotted lines in Fig. 4, and in full lines in Fig. 5, by a pull upon the knob '6 Instead of dividing the race-way into separate arcs as thus far described, with remov-- able or hinged sections for introducing the third or greater number of shuttles, the raceway may consist of two or more separable circular sections or a combination of races 1 I, as illustrated in Figs. 7 and 8. The section or race 1 is stationary and provided with pins 1 which engage openings through the adjustable section I, which may be adjusted along said pins and secured at any desired distance apart thereon or with reference to the stationary section, by means of set screws i, or in any proper manner. To adapt the needles to be correspondingly adjusted, I provide means for securing the needles in any desired position with reference to the positions of the shuttles and shuttleraces, as illustrated in Fig. 7. This may be done in a number of Ways, but I preferably provide an arm or needle-holder 0, having the usual needle-sockets and socketed head to receive the needle-bar with a lateral extension 0 oltset as at 0 so as to set the needles carried thereby in line with the needles in the usual needle-sockets, and secure upon said extension sliding clips G 0 having sockets and set screws therein as shown for the attachment of the needles. The clips may be secured at any desired point along the supporting bar by set screws 0 To remove the intermediate shuttle in Figs. 1 to 6, the driving wheel of the machine should be turned toward the operator until the needle-bar is at its lowest point, whereupon the bolt L, may be drawn out and given a slight turn whereby it will be locked so as to prevent it from being forced inward by the recoil of the spring. Then by a downward pull upon the knob 2' the section or segment l of the shuttle-race may be brought to the position shown in dotted and full lines in Figs. 4 and 5, respectively, in which position the shuttle K, may be easily opened for changing bobbins or removal entirely. Figs. 1, 2 and 4 show the shuttle race closed, and Figs. 5 and 6 show the race opened for refilling. The dotted lines in Fig. 7 show the combination shuttle race closed. The full lines show the race opened by sliding the outer section I along on the bars I to permit easy access to the intermediate shuttle or shuttles either for removal or refilling with bobbins.

It will be understood of course that the invention in either form is not restricted to the use of three needles, but additional needles may be introduced by making similar combinations of shuttle-races and needles corresponding ad libitum. Fig. 7 illustrates the adaptability and scope of this plan of multiplying needles and rendering the same adjustable so as to change the spacing of the needles to correspond with the spacing of the shuttles, which is a very desirable featureot the invention.

By providing the needle holder with adj ustable needle-sockets, asillust-rated in Fig. 7, it is adapted to be used interchangeably with a needle holder of ordinary construction, as illustrated in Fig. 3, and also in connection with multiple shuttles of different widths,re quiring the needles to be placed at dilferent distances apart; provision being made for setting the needles to correspond with the distance between the shuttles.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
